Order LookupStraight-Flute Drill Bits
Available149 products
Straight-flute drill bits are stronger than spiral-flute drill bits and resist breaking when drilling into hard and abrasive materials, such as hardened steels with a Rockwell hardness of 35 to 60 HRC. The bits provide free-cutting action, generate minimal heat during drilling, and leave a smooth finish on the hole without requiring a reaming pass. The bits' straight flutes help with chip evacuation in horizontal drilling applications.

Coolant-Through AlTiN-Coated Carbide Straight-Flute Drill Bits
These straight-flute drill bits have an AlTiN finish that withstands high temperatures and protects the bits from wear during high-speed, dry machining applications with difficult-to-machine ferrous metals. Carbide drill bits provide excellent hardness, wear resistance, and heat resistance. They require a rigid setup such as a drill press. These drill bits have holes that allow coolant to flow to their tip to reduce heat and help clear chips during drilling.
